The Wireless Innovation (News - Alert) Forum, a non-profit international
industry association dedicated to driving the future of radio
communications and systems worldwide, today announced the dates for a
preview of changes included in the much anticipated SCA 4.1 Standard.
The event, held in cooperation with the Joint Tactical Networking Center
(JTNC), will occur in the Washington, DC area following MILCOM on 9-10
October 2014. More event details will be announced later this summer.

The Forum's Coordinating Committee on International SCA Standards has
been working as public liaison for the JTNC to provide input on
remedying issues with SCA 4.0 through production of SCA 4.1 since the
November 2013 kick-off workshop (http://groups.winnforum.org/p/cm/ld/fid=403).
Working groups within the Committee have produced several documents
currently up for vote including:

SCA 4.1 Scalable Components

This document has been prepared by the Forum's SCA 4.1 Backwards
Compatibility Task group to propose changes to the SCAv4.0.1
specification to add support for component scalability. This will
allow component developers to choose whether or not to implement
some of the standard sub-component interface. The scalability will
also be used to support the different profiles of the
specification.

SCA 4.1 Scalable Manager Components

This document has been prepared by the Forum's SCA 4.1 Backwards
Compatibility Task group to propose changes to the SCAv4.0.1
specification to add support for scalability of the manager
components. This will allow developers to choose whether or not to
implement all of the manager interfaces. The manager scalability
will also be used to support the different profiles of the
specification.

SCA 4.1 Naming Conventions

This document has been prepared by the Forum's SCA 4.1 Backwards
Compatibility Task group to propose changes to the SCAv4.0.1
specification to use a naming convention for the names of the
interfaces and components. The goal is to improve readability of
the next release of the specification

SCA 4.1 Application Backwards Compatibility

This doument package has been prepared by the SCAv4.1 Backwards
Compatibility Task Group to provide comments to the JTNC on the
modifications to SCA v4.0 necessary to support backwards
compatibility with SCA v2.2.2.

SCA 4.1 AEP Specification

This document has been prepared by the SCAv4.1 AEP Improvements
Task Group to define POSIX AEPs for interaction between SDR
Applications and OE in resource constrained environments. Two Base
AEPs functions groups, the Lightweight (Lw) and the
Ultra-Lightweight (ULw), are defined, with functions Groups A and
B being possibly added as support features. The documents contains
normative content for Base AEPs functions groups and the
additional functions groups, plus support sections giving SCA-like
contents overview tables and detailed rationale for the design
choices. The specification is a converged solution elaborated
between developers who worked to generate a unified content
leveraging previous achievements in this area from JTNC Standards
and ESSOR.

SCA 4.1 Application Mixture Backwards Compatibility

This document proposes changes to the next SCA specification to
increase the level of backwards compatibility via an optional unit
of functionality (UOF) to support applications composed of a
mixture of SCA 4 and SCA 2.2.2 components. This will allow
developers to perform a more incremental transition from SCA 2.2.2
to SCA 4.

Additional project ballots coming up for vote in the near future,
include: SCA 4.1 Platform Component Late Registration Committee Ballot
and SCA 4.1 IDL Profile Specification Committee Ballot. These documents
will be delivered by the WInnForum to the JTNC once all comments
received during balloting are resolved and balloting completes.

Wireless Innovation Forum member representatives have initiated and led
multiple work efforts that promote their organization's specific
objectives through the creation of reports, recommendations and
specifications that are widely used by the advanced wireless community.
The importance of these "work products" is reflected in the fact thatover
22,000 individual documents were downloaded from the Forum's Work
Productsdocument
library in 2013 alone.

Supported by platinum Sponsor Selex
ES, and Media Sponsor Thales (News - Alert), WInnForum has several
working groups focusing on projects related to SCA and Spectrum
Innovation. Visit http://www.WirelessInnovation.org
